What is Dry Lube oil Sump? A dry sump system uses an external reservoir to store the engine oil, separate from the crankcase.

What is Dry Lube oil Sump 

Operation: The oil pump draws oil from the sump, circulates it through the engine, then sends it to the external reservoir. A separate scavenge pump then transfers oil from the crankcase back to the external reservoir.

Advantage of Dry Lube oil Sump 

  • Larger oil capacity for improved cooling and lubrication, especially under high-performance conditions.
  • Reduced risk of oil starvation due to g-forces.
  • Allows for better oil temperature control by placing the reservoir away from the hot engine.

Disadvantage of Dry Lube oil Sump 

  • More complex design with additional components like the external reservoir and scavenge pump.
  • Increased cost and maintenance requirements.
  • Potential for increased leakage points with additional hoses and connections.

What is meant by a dry sump lubrication system?

A dry sump lubrication system is a complex lubrication system used in internal combustion engines. It uses multiple, separable oil reservoirs instead of a single sump. An external pump, located close to the engine, supplies the oil under pressure to the engine’s lubricating system. This system has improved oil control, which improves engine performance and prolongs engine life and greatly reduces the risk of engine failure due to lack of oil.

What is the use of dry sump lubrication system?

Dry sump lubrication systems are used to improve engine performance, durability, and efficiency by providing a continuous supply of clean, cooled oil to the engine parts. It also helps reduce noise and vibration. This system helps ensure adequate oil circulation to all engine components by using additional pumps and oil galleries in the engine sump or pan, and helps maintain cooler oil temperatures by providing increased oil capacity and improved oil drainage.

Why is it called a dry sump?

A dry sump system uses an external reservoir to store oil rather than an internal oil pan or sump, hence its name. This external reservoir is designed to separate the oil from the engine’s crankcase and prevent it from becoming part of the combustion process. This is in contrast to a traditional wet sump system, which uses an internal sump that collects oil and allows it to mix with air and fuel.

Choosing the Right System: Dry sump vs Wet sump

  • Wet sump: Suitable for most everyday driving situations in passenger cars and motorcycles, Big Generator, Power producing Engine,
  • Dry sump: Preferred for high-performance applications like racing engines, airplane where oil starvation and temperature control are critical.

FAQ’s

What is wet sump and dry sump?

Wet sump is an engine lubrication system in which oil is stored in a pan attached to the bottom of the engine, and is circulated using a pumps. In a dry sump system, the oil is stored in a remote tank, and the oil is driven using scavenge pumps and pressure pumps, sending the oil to various points of the engine. Dry sump systems are more efficient as they can hold more oil, can better handle high-G forces and provide better engine cooling.

What is the function of the sump?

The sump is a covered tank that collects and stores water, usually at the base of a building. Its main function is to ensure proper drainage in areas that have inadequate fall or too much water saturation. The sump also helps to protect homes and buildings from flooding by collecting excess water and redirecting it away from the building’s foundation. By using a sump pump, it is also possible to pump water from a sump to areas such as gardens, ponds, or other locations.

What is called dry sump?

A dry sump is an oiling system found in rotary and piston engines. This system uses an external reservoir, a series of dry sump pumps, and a scavenge pump to manage oil, capture unwanted oil vapors, and lubricate the engine components. Dry sump systems are typically used in demanding applications such as racing and extreme performance applications, where a higher level of control of the oiling system is required.

What are the two types of oil sumps?

The two types of oil sumps are wet sump oil systems and dry sump oil systems. A wet sump system stores all of the oil in a reservoir under the engine, and uses an oil pump to pressurize and circulate it throughout the engine. A dry sump system uses multiple reservoirs to store oil, along with an external pump to pressurize and circulate oil throughout the engine.

Which cars have dry sump?

Dry sump systems are often used in high-performance vehicles. They help to improve engine performance and longevity. Some of the cars that feature dry sump systems include the Ford Mustang GT, Chevrolet Corvette, Audi R8, Mercedes-AMG GT, and Porsche 911 Turbo.
